If your character is confused or becomes a Werecreature of any kind and auto-attacks do not use the game engine in any way to prevent their behavior. You are not meant to be able to control their behavior during this period and any attempt to do so will be considered a violation of the rules.

Better still when in hybrid form and confused you attack a high lvl NPC priest who gets infected, you gain control - run away from them and next you both shift and both start attacking everything and each other!!
